To all whom it may concern: e

Be itknown that I, OTHo'Mh om, citizen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New ,York, have in, vented certain new and useful Improvements in Spot-Light Mountings, of whichthe following, takenin connection with the accompanying drawings, is a specification.

The invention relates to spot-light mountings for automobiles and other vehicles and the inventionteonsists in providing a spotlight mounting .which is adaptable by means of ball and socketjoints to a three-point adjustment, that is, a ball and socket joint between the outer end of the bracket'arm and the socket clamping plates, and between the lower end of the lamp supporting standard and said socket clamping plates, so as to adjust the position ofsaid standardand the lamp supported thereon in any direction by simply releasing 'theclampingthold ofthe.

two socket clamping plates from the 'ball ended bracket or standard :or :both bracket and standard, a fulcrum being provided on said ball socket plates to provide a definite third point of contacting leverage'between said plates; and the invention consists in here1nthe novel features and combinations after set forth and claimed.

In the drawings, Figure 1 is an elevation of the spotlight mounting atlEEIClldtO a.

standard, as for example the supporting standard for a windshield on an automobile, showing different adjustments of the lamp in dotted outline. Fig. 2 is a sectional view at line 2-2 in Fig. 4, showin the construction and arrangement of the amp supporting standard with the ball-shaped lowerend. Fig. 3 is, a perspective view of the socket clamp for the standard and bracket ball ends, to connect the same in such a manner as to permit different adjustments. Fig. 4 is a lengthwise sectional View of a portion of the reflector and the casing therefoi and the supporting tubular extension showing the lamp supporting tube adjustably mounted therein. Fig.5 is an dgewise elevation of the socket clamp; and Fig. 6 is an elevation of the innerside of one of the clamping plates showing the triangular clamping tension on the ball shaped extremities of the standard and bracket.' Fig. 7 is a top plan elevation of thesu'pporting bracket removed from the standard.

1 Like characters of reference referto corresponding parts in theseveral views.

he numeral 10 designates a supporting standard, as for-example a windshield or other upright'around which the bracketll may beattached by means of the metal strap .12 and screw bolts 13 to thereby hold the bracket 11 in the horizont-alposition with its ball shaped end 11 extending at right angles to the standard 10. I

The lamp 15 is provided .With a reflector 16 which'is supported within the lamp casing 17. The casing 17 of thelamp 15 is supported by arearwardly"extendingtubular a portion around 'which the upper end of the,

standard 18 slidably fits so that said tube 17 may be slipped within the opening in said upper end of the standard 18 and held firmly in position by the set screw 19.

, A second tube 20 is slidably mounted within the tubelT and a second set screw 21 is provided in the upper portion of the standard 18 to hold the tube 20, a slot22y being" provided'in the tube 17 so that either one of said set screws 19 or 21 may be re-, n leased sufiiciently to slidably adjust either the entire lamp 15 in the standard 18, Oh

the electric lam-p 23 with 'itslight 24 within,

the tube 17 and reflector 16 so that anyd i. sired adjustment of said light 24 to or front 1 the focus of the reflector 16 may be quickly.

and easily attained.' The tube 17 has a sl'ot ted rear end to provide spring fingersland a removable spring adjusted ca'pto open and close the same for approach to the switdhf '25 and wire connections 27 and 28, said wire connections entering through. a slotted ,opeiiing in the tube 17 which ermits ofthe fo'r;

ward movement of the tu e 20. j r The inner tube 20 preferably provided with an electric switch 25' having the compressible contact pins 26 extending out on opposite sides. The connecting wires 27 -and 28 are attached to the rear endv thereof and'connected through the tube 20 to the lam v socket 29, thus the lamp 23 can be adjuste as hereinbefore stated by simply releasing the set screw 21.

In order to adjustably connect the bracket 11 with its ball-shaped end 14 with the standard 18, a ball-shaped lower end 30 is provided on said standard 18 and a pair of plates 31 and 32 are connected by means of a thumb screw 33. Said plates 31 and 32 have the sockets 34 for the ball 14 and 35 for the ball 30 to clampingly hold the same.

A third point or teat-shaped fulcrum 36 isprovided on plate '31 so as to provide the three points of contact A, B and C when the set screw 33 tightens the plates 31 and 32 onto said balls H and 30. The slotted opensockets 34 and 35 as to turn the lamp 1 5 into almost any desired position, and that the fulcrum point 36 gives a three point compression upon said balls 1% and 30 so that the lamp is firmly secured in any of the desired positions; Also that the electric light 94: may be adjusted to the reflector 16 in any desired position.

I claim as new 1. A lamp mounting comprising a bracket arm and means for attaching to a support thereon, a ball-shaped outer end on said bracket arm, a. standard having a ballshaped lower end, means for attaching a lamp on the upper end of said standard, clal'nping plates spaced throughout their main portions and shaped in oppositely placed spaced sockets to receive said ballshaped ends therein, a fulcrum point on one of said plates contacting the opposite plate to give a strong and even clamping leverage on said ball-shaped ends, and means for drawing said plates toward one another to therebyclamp said ball-shaped ends.

2. A lamp mounting comprising a bracket arm having a ball-shaped outer end, a standard having a ball-shaped lowerend, a lamp supported on said standard, spaced triangular plates having oppositely placed sockets on two of the corners thereof to receive said hall-sha )Ed ends therebetween, a projection on the t ird corner of said triangular plates to form a fulcrum point for a clamping hold for said plates on said ball-shaped ends, and a screw central of said triangular plates to draw said plates toward one another and hold said standard in an adjusted position as to said bracket.

3. Alamp mounting comprising a bracket arm and a support there-for, a ball-shaped outer end. on said bracket arm, a; standard and means thereon to support a lamp, a ballshaped lower end on said standard, spaced clamping plates having a triangular three point bearing two of said points being on said ball-shaped ends and the third point upon one another to form a fulcrum, and a screw connecting said clamping plates between sa-id ball-shaped ends and said fulcrmn to give said plates a strong leverage on said ball-shaped ends. i

4. A lamp mounting comprising a bracket arm and a support therefor, a ball-shaped outer end on said bracket arm, a standard and means thereon to support a lamp, a ball-shaped lower end on said standard, triangular shaped clamping plates having sockets in oppositecorners to receive said ball-shaped ends therein, said sockets having slotted openings to adjust the relation of said standard and arm to one another and said clamping plates, a teat-shaped projection 'on the third cornerof one of said plates having a seat in the third corner of the opposite plate to form a fulcrum point for said sockets and ball-shaped ends, and a manually adjusted screw to clamp said plates upon said ball-shaped ends and one another.

5. A lam) mounting comprising a lamp having a tu ular rear extension with a second tube slidaibly mounted therein to support the electric light, a standard engaging around said tubular rearderitension to support said lamp, two set screws in said stand: ard to adjustably hold both said tubular extension and the tube therewithin, one tube to each set screw, a ball-shaped lower end on said standard, a. bracket arm having a ball-shaped outer end, plates having sockets to clampingly engage said ball-shaped ends to adjustably connect the same, a fulcrum point on said plates to give a three-point bearing therefor, and a manually operable screw inserted through said plates between said fulcrum point and said ball-shaped ends to adj us'tably clamp said plates thereon.

In testimony whereof I have allixed my signature in the presence of two witnesses.
